New submission from Ronan Pigott <rpig...@berkeley.edu>:
pydoc references the value of both MANPAGER and PAGER variables when selecting a command to present the user with documentation. Those values are passed directly to subprocess.Popen. However, MANPAGER may contain arguments that need splitting, and is explicitly documented as such in the `man 1 man` manpage: > If $MANPAGER or $PAGER is set ($MANPAGER is used in preference), its value is > used as the name of the program used to display the manual page. [...] The > value may be a simple command name or a command with arguments, and may use > shell quoting (backslashes, single quotes, or double quotes). It may not use > pipes to connect multiple commands; if you need that, use a wrapper script > [...] pydoc should perform word splitting a la shlex.split on the values of MANPAGER and PAGER to retain compatibility with man. ---------- components: Library (Lib) messages: 360332 nosy: Brocellous priority: normal severity: normal status: open title: pydoc: Use of MANPAGER variable is incorrect type: enhancement versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39400> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
